Chapter 320 Eat seafood and drink beer

After agreeing to this request, Liu Hua felt a little regretful. There were no scientific research tasks in the factory at the moment, so he put all his energy into this small request.

But what exactly is the so-called cost-effective and easy-to-use equipment? You can’t design an engineer shovel, although the army still has an engineer shovel as standard, but when it comes to digging trenches, it’s not the turn of the engineer shovel.

Liu Hua sighed at home all day long. It was difficult for him to tell his wife about this matter, so he had to deal with it alone.

One day when he was really bored, he picked up a military magazine that his son had left on the table and read it. As he was reading, Liu Hua got inspired.

In the absence of aircraft carriers and advanced fighter jets, our country has two national treasures, one is the Dongfeng Express, and the other is the nuclear submarine.

It is definitely not Liu Hua’s turn to design Dongfeng Express. Not to mention the up-and-coming talents, Mr. Qian is still here.

It is a great regret in life that Liu Hua and Mr. Qian have never met each other. I quickly retracted my thoughts.

Since it is not Liu Hua’s turn to make any changes to Dongfeng Express, he can only focus on nuclear submarines.

Of course, he had no part in the design of nuclear submarines, but in this era, our country’s nuclear submarines have a fatal flaw.

The noise is too loud and is always ridiculed by the West, who say it can be heard with just the ears. If a nuclear submarine loses its stealth, its deterrent capability will be greatly weakened.

To eliminate these noises, it is necessary to use the technology of large-scale use of sound-absorbing tiles and use more advanced propulsion technology.

Coincidentally, Liu Hua actually knew something. For example, our submarines later all used pump-propelled technology, which could greatly reduce the noise made by submarines while moving.

Compared to submarines, these two things are indeed good equipment that don’t cost much.

We have decided on these two. If our submarines are equipped with them, they can travel silently in the ocean. Let’s see how the Americans dare to show off.

Even if they dare to show off, they wouldn’t dare to show off as blindly as they are now.

The points for these two things are really expensive. Liu Hua did not redeem the most advanced ones, but the technical equipment level of our country around 2010. The anechoic tile technology is the technology of the United States in the 1990s, which is the technology used on their Seawolf-class attack submarines that are about to be put into service.

Liu Hua can synthesize sound-absorbing tiles made of polyurethane and glass fiber in his home laboratory.

Liu Hua is very experienced in exchanging techniques one by one, otherwise his brain would not be able to bear the input of so much data. Although he is very strong now, the data of this kind of high-tech technology is very large. Every time he exchanges it, he feels dizzy for a while.

After more than two months, Liu Hua finally synthesized polyurethane and produced qualified glass fiber, which also required aluminum plates for processing.

These things cannot be made at home, so I have to contact the liaison officer in the General Logistics Department again and find a factory that can process them.

“Engineer Liu, didn’t you say that you wanted to research some practical gadgets that don’t cost much money?”

“correct.”

The contact officer frowned and said, “What’s the use of this thing you’ve synthesized now? Is it practical?”

Then he went on to say, “You can synthesize it in your home laboratory, so it probably doesn’t cost much, but I can’t see what you use it for.”

“Silencer tiles.” These three words made the liaison officer fall into deep thought. After a while, he said, “Silencer tiles, what are they used for? It sounds like they can block out sound, but what equipment do we have that needs to be silenced? The sound was detected before it even reached the radar. This is totally impractical.”

Liu Hua pointed to the sky: “We don’t need it up there. We need to be invisible up there.”

He pointed to the ground again: “Ground equipment does not need to be silent. Ground equipment is generally used face to face. If you can hear the sound, you can basically see the person.”

The liaison officer said suspiciously, “For use at sea? It shouldn’t be needed at sea. Even in the past era of giant ships and cannons, the sound of the cannons fired was more than ten kilometers away, and it was impossible to hear them.”

Liu Hua pointed to his feet and said: “Below the sea surface, submarines are usually discovered using sonar.”

The liaison officer tapped his head and said, “I remember now. It seems that Western submarines are also using anechoic tile technology. It was first used by Hans.”

Liu Hua nodded: “You should know how loud our submarine is.”

The contact person said anxiously: “You shouldn’t be working on such important technology at home. Has the information been leaked?”

“What are you thinking?” Liu Hua said dissatisfiedly, “How could I not know how important this technology is? I have a safe here, and who would have thought that I would make these things at home?”

“That’s right.” The contact person said quickly, “Now I know. You can’t keep these technical documents here. I’ll find someone to pretend to be a moving company and move these documents away. Please pack them up quickly.”

“It’s not a lot, two or three boxes will be enough.”

The contact person nodded and said, “Wait a moment, I’ll find someone to escort them with live ammunition.”

In less than thirty minutes, a group of plainclothes men with flat heads entered Liu Hua’s yard and left carrying three large boxes.

The liaison officer drove Liu Hua directly to the General Logistics Department, chattering all the way: “Next time you research such important technology, can you please let me know first? I will be caught off guard. If this gets leaked, my life will be over.”

Liu Hua was drinking tea in the reception room. It was said that the tea was obtained by the liaison from the leader’s office. The leader, who was also the leader’s leader, gave it to him, but he was reluctant to drink it. In the end, it was given to Liu Hua.

Before I finished my cup of tea, a man carrying a star came in with a smile on his face: “Engineer Liu, you really gave me a big surprise. Our submarines are currently unable to suppress noise. We are now actively contacting the big bear and want to introduce the sound-absorbing tile technology. If your experiment is successful, it will save us a lot of money.”

“It’s my honor.” Liu Hua said modestly, “It’s my honor to forge swords for my country.”

The leader said approvingly: “You are worthy of the praise given by the leader as the backbone of industry. I have just coordinated a factory to process the sound-absorbing tiles, but you may have to go on a business trip for a while.”

“where?”

“Jiaozhou Bay.” The leader smiled and said, “I have also told the experts at the submarine base that they are very interested in the anechoic tile technology and hope to join us in joint research.”

“Of course I welcome you. After all, you are a professional submarine researcher.”

The leader waved his hand and said, “You can bring your family with you. The scenery there is quite nice. Eating seafood and drinking beer is also a great pleasure in life. Just think of it as traveling with your family.”
